I'm trying to add a field on res.partner, but everytime that I upgrade the module the field just doesn't appear, even on postgresql...
And after I restart the server, I got a error psycopg2.errors.UndefinedColumn: column res_partner.distrito does not exist

distrito = fields.Char(string='Bairro') <= field problem

I have no idea what is happening. 

My code:

from odoo import models, fields, api

class ResPartner(models.Model):
 _inherit = 'res.partner'

tipo_cliente = fields.Selection( string= 'Tipo do cliente', selection=[('gov','Governo'),('pri','Privado')])
tipo_contato_id = fields.Many2one( string='Tipo do contato', comodel_name='tipo.contato')
orgao_id = fields.Many2one( string='Orgão', comodel_name='orgao.governo')
distrito = fields.Char(string='Bairro') #<- field that doesn't appear
partido_id = fields.Many2one( string='Partido', comodel_name='partido.governo')
departamento_id = fields.Many2one( string='Departamento', comodel_name='departamento')
is_customer = fields.Boolean( string='É cliente?', default=False)

class Departamento(models.Model):
 _name = 'departamento'
 _description = 'Departamento'

name = fields.Char(string='Nome do departamento')

class TipoContato(models.Model):
 _name = 'tipo.contato'
 _description = 'Tipo do contato'

name = fields.Char(string='Tipo')

class OrgaoGoverno(models.Model): 
_name = 'orgao.governo'
 _description = 'Orgão do governo'
name = fields.Char(string='Nome')
​

class PartidoGoverno(models.Model):
 _name = 'partido.governo'
 _description = 'Partido'
name = fields.Char(string='Sigla')
